Question

我在部署我的Web应用程序时遇到错误，当我调试时发现我的.jar文件有问题
我确信我的部署程序是正确的部署应用程序时出错：

java.lang.AbstractMethodError：Method I / Z.compare（Ljava / lang / Object; Ljava / lang / Object;）我是抽象的 I.Z.compare（未知来源）

如果我反编译我的.jar文件，这个I.Z.Compare方法如下所示

我也有正确的.jar文件，但没有源代码。 I.Z.compare如下所示：

对于前.jar文件。负责生成此方法的代码如下所示：

static Comparator comparator()
    {
      return new Comparator()
        {
          public int compare(Object o1,Object o2)
          {
            return Range.compare((Range)o1,(Range)o2);
          }
        };
    }

比较功能中存在一切。仍然没有反映在.jar文件中下面是我的Build.xml：

在build.xml文件中。有一个混淆器正在重命名函数并分析它的日志，我发现我对流的理解是正确的，但是混淆器的日志文件中有一个错误：

在Classpath
上找不到java / util / Comparator.class

如果您需要更多信息。我可以提供。我花了很多时间搞清楚这一点。请帮帮我！
